14.3.5.1
Pin assignment / conductor coloring Connector I (3-terminal)
Connector for low-level advance warning or empty report
Fig. 14.6 Connector I (3-terminal)
In the event that the empty report is not used, contact 3/4 must always be bridged! The
WARNING
protective cap provided for this (see chapter 7.2.1) creates the bridge between he contacts
and must be attached in this case.
The empty and reserve report input can be inverted in the "Configuration / Low-level

contact" menu. (see chapter 10.3.8)
14.3.5.2
Pin assignment / conductor coloring Connector II (5-terminal)
Connector for pulse / standard signal input and metering lock
Fig. 14.7 Connector II (5-terminal)
The metering lock input is only active if it has been previously set in "Configuration /
NOTE
metering lock" menu. (see chapter 10.3.7) The batch function (see chapter 10.3.15) and
metering monitoring (see chapter 10.3.13) must also be configured.

Metering rates
The reproducible metering accuracy is approx. ± 3 % at a minimum 30 % stroke length under
invariable conditions. Due to the characteristics of the pump, higher output can be produced
until the operating temperature is reached.
Accurate metering can be achieved by observing the following points:
a) All metering output data refer to measurements with water at 20 °C as well as a constant
supply voltage and a warmed-up operating condition of the metering pump.
b) If there is pre-pressure on the suction side, the pressure difference between the suction
and the pressure sides must be at least 0.1 MPa (1 bar). The water column on the
metering pump must be protected by an appropriate valve arrangement.
A pressure control valve or a metering value is not an absolutely hermetically sealing
NOTE
shutoff device.
Metering stroke adjustment may only be performed with the pump running if the stroke
